Event Details

For three decades, climate policy proposals have focused on a single approach: reduce emissions of carbon dioxide (CO₂) and other greenhouse gases. Since 1990, however, global CO₂ emissions have increased 60 percent, atmospheric CO₂ concentrations have raced past 400 parts per million, and temperatures increased at an accelerating rate.

On Thursday, June 4, 2020, RFF hosted a webinar featuring Joseph E. Aldy and Richard Zeckhauser, both scholars at Harvard University’s Kennedy School. They discussed their recent research evaluating a three-pronged strategy for mitigating climate change risks: adding adaptation and amelioration—through solar radiation management (SRM)—to the emissions mitigation approach. This RFF Live event featured a discussion on SRM’s potential role in offsetting warming at low cost, and also assessed the concern that SRM would diminish traditional emissions mitigation incentives.

With this Common Resources Q&A blog post, Aldy and Zeckhauser answer the questions about solar radiation management that attendees asked at this event. These questions could not be addressed live, due to time constraints. Some questions have been edited for clarity and length.

Speakers

  • Joseph E. Aldy, University Fellow, Resources for the Future
  • Richard Zeckhauser, Professor of Political Economy, Harvard Kennedy School
